CLINICAL TRIALS PROFILE FOR VIBEGRON

All Clinical Trials for VIBEGRON

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01314872 ↗	A Study of the Efficacy and Safety of Vibegron (MK-4618) in Participants With Overactive Bladder (OAB) (MK-4618-008)	Completed	Merck Sharp & Dohme Corp.	Phase 2	2011-03-31	This is a 2-part study to assess if vibegron (MK-4618) reduces the number of daily urinations more effectively than placebo in participants with overactive bladder (OAB). The primary hypothesis of the base study is that administration of vibegron demonstrates a dose-related reduction, compared with placebo, in average number of daily micturitions in participants with OAB after 8 weeks of treatment.
NCT01500382 ↗	A Study of the Pharmacokinetics and Pharmacodynamics of Vibegron (MK-4618) in Women With Overactive Bladder (MK-4618-004)	Terminated	Merck Sharp & Dohme Corp.	Phase 1	2012-02-27	The study is designed to investigate the effects of the investigational drug vibegron (MK-4618) compared to placebo on maximum urinary bladder capacity in women with overactive bladder. The study will also evaluate the safety and tolerability of multiple oral doses of vibegron in women with overactive bladder. Overactive bladder is best described as urgency and frequency of urination, with or without involuntary urination and/or the need to awaken during the night to urinate. The primary efficacy hypothesis is that vibegron is superior to placebo with respect to change from baseline in maximum cystometric capacity at 2 hours postdose on Day 7 (i.e., steady state) in participants with overactive bladder. A true mean increase (vibegron/placebo) of 25% in bladder volume is expected. The primary safety hypothesis is that administration of multiple oral doses of vibegron is sufficiently well-tolerated in participants with overactive bladder, based on assessment of clinical and laboratory adverse experiences, to permit continued clinical investigation.
NCT01628042 ↗	A Single Dose Study of the Pharmacokinetics of Vibegron (MK-4618) in Participants With Renal Insufficiency (MK-4618-014)	Completed	Merck Sharp & Dohme Corp.	Phase 1	2012-07-16	This study will investigate the impact of impaired renal function on the plasma pharmacokinetics of vibegron (MK-4618) to guide use of vibegron in clinical trials in participants with overactive bladder and to guide recommendations on potential dosing adjustments for individuals with varying degrees of renal impairment.
NCT01737684 ↗	A Single-Dose Study of the Pharmacokinetics of Vibegron (MK-4618) in Adults With Hepatic Insufficiency (MK-4618-013)	Completed	Merck Sharp & Dohme Corp.	Phase 1	2013-01-15	This study will investigate the pharmacokinetics of a single oral dose of vibegron (MK-4618) administered to participants with moderate hepatic insufficiency and healthy participants matched for age, gender, and body mass index (BMI). Participants may be enrolled with mild hepatic insufficiency.
NCT03492281 ↗	A Study to Examine the Safety and Efficacy of a New Drug in Patients With Symptoms of Overactive Bladder (OAB)	Completed	Urovant Sciences GmbH	Phase 3	2018-03-26	This study is designed to evaluate the safety, tolerability, and efficacy of vibegron administered once daily in patients with OAB.
NCT03583372 ↗	An Extension Study to Examine the Safety and Tolerability of a New Drug in Patients With Symptoms of Overactive Bladder (OAB).	Completed	Urovant Sciences GmbH	Phase 3	2018-06-14	This study is designed to evaluate the safety, tolerability, and efficacy of vibegron administered once daily in participants with OAB for up to 52 weeks.
NCT03806127 ↗	Study to Evaluate the Efficacy and Safety of Vibegron Administered Orally for 12 Weeks to Women With Irritable Bowel Syndrome	Completed	Urovant Sciences GmbH	Phase 2	2018-12-31	This study will evaluate the efficacy and safety of vibegron, a beta-3 adrenergic receptor (β3-AR) agonist, in the treatment of pain associated with irritable bowel syndrome (IBS) due to IBS with predominant diarrhea (IBS-D) or mixed episodes of diarrhea and constipation (IBS-M).
